A novel picolinate-iron(III) compound, Fe(C6H4NO2)2(OH) (1), was synthesized from an aqueous solution of a picolinate-iron(II) complex. Compound 1 was obtained by a thermal treatment of the picolinate-iron complex aqueous solution, whose pH was adjusted to 3–7, containing more than twice molar picolinic acid (Hpa) to Fe at 353 K for 72 h. When the iron aqueous solution in the presence of more than six times molar Hpa to Fe at pH 2–5 was heated, Fe(C6H4NO2)3·H2O (2) appeared. Millimeter-sized yellow-green single crystals of 2 could be obtained by the heat treatment of the picolinate-iron aqueous solution, whose pH was adjusted to 3, with Fe2+:Hpa = 1:10 at 373 K for 72 h. Formation mechanism of 1 and 2 was also discussed through investigations of relationship between synthesis conditions and products. Our approach opens a promising new route for preparation of precursors for synthesis of high functional ceramics and development of new organic–inorganic hybrids.
